How to open a RAR file
- Choose your .rar or .7z file. The format is recognised from the file itself, so a wrong extension doesn't matter.
- The file list shows every file with its unpacked size. Type part of a name to find one in a big archive.
- Tap Download next to a file, or Download all as ZIP to keep the folders.
RAR, RAR5 and 7z
RAR is the format made by WinRAR. Newer archives use version 5 (RAR5), older ones version 4; both open here. 7z is the format of the free 7-Zip program. Phones and computers open ZIP files on their own but often need an extra app for RAR and 7z (recent versions of Windows 11 can read them), which is why a browser tool is handy. If you want a file that anyone can open, use RAR to ZIP.
Safe file names
Names inside an archive can try to point outside the folder they're unpacked into. The extractor cleans every name first, and it never follows links:
- An entry called
..\..\Windows\evil.dllis saved asWindows/evil.dll, inside the archive's own folder. - Two files that would both be
report.pdfbecomereport.pdfandreport (2).pdf, so neither is lost. - Symbolic links and device files are skipped and counted.
Opening an archive is safe, but a file inside it can still be harmful. Scan downloaded programs (.exe, .apk, .bat) with your antivirus before running them, as you would any download.
Limits
Archives up to 300 MB open in the browser, with at most 5,000 files, 512 MB for one file and 1 GB unpacked in total. These are checked before anything is unpacked, using the sizes the archive declares, so a tiny archive that claims to hold many gigabytes is refused instead of freezing your phone. For ZIP files, use the ZIP extractor.
